The Liddell, Scott, Jones Ancient Greek Lexicon (LSJ) is perhaps the best known Ancient Greek-English dictionary. Here you can find a wiki implementation.The wikification of LSJ was no mean task but we hope that the
extra features provided by the wiki set-up will enhance the user
experience. Some of these features (like the indexes) were made possible through the use of Semantic Mediawiki extensions.
Different types of transliterations and word forms
were used, so that everyone is happy: Ancient Greek scholars, speakers
of Modern Greek, people who prefer transliterated Greek or Beta Code. For example, you will get results on the search box no matter
whether you type in polytonic Greek, monotonic Greek, Greek without any
accents at all, or transliterated Greek.
